“…The adsorption process is typically cycled between two beds of adsorbents; one bed is adsorbing CO 2 while the other is being regenerated. In the regeneration process, CO 2 can be desorbed by either pressure swing adsorption (PSA) (pressure reduction) (Ishibashi et al, 1999;Gomes and Yee, 2002;Yokoyama, 2003), temperature swing adsorption (TSA) (temperature increase) (Drage et al, 2009;Tlili et al, 2009), electrical swing adsorption (ESA) (Grande and Rodrigues, 2008;Grande et al, 2009), which adjusts the electric current passed through the adsorbents, or vacuum swing adsorption (VSA) (Chaffee et al, 2007).…”

“…Over the years it has been demonstrated that PSA technology can be used in a large variety of applications: hydrogen purification [58][59][60][61][62][63][64][65][66][67][68][69][70][71][72], air separation [57,[73][74][75][76][77][78][79][80], OBOGS (on-board gas generation system) [81], CO 2 removal [82][83][84], noble gases (He, Xe, Ar) purification [85][86][87], CH 4 upgrading [31,34,37,40,42,[88][89][90][91][92][93][94][95][96], n-iso paraffin separation [5,[97][98][99]…”

Pressure swing adsorption (PSA) is a well-established gas separation technique in air separation, gas drying, and hydrogen purification separation. Recently, PSA technology has been applied in other areas like methane purification from natural and biogas and has a tremendous potential to expand its utilization. It is known that the adsorbent material employed in a PSA process is extremely important in defining its properties, but it has also been demonstrated that process engineering can improve the performance of PSA units significantly. This paper aims to provide an overview of the fundamentals of PSA process while focusing specifically on different innovative engineering approaches that contributed to continuous improvement of PSA performance.

“…The selection of this water vapor range covers the typical water vapor range of 8 -12% in flue gas. 27 In this case, moisture was introduced into the gas stream by dispersing the 15% of CO 2 gas through a water bath.…”

A relatively new mesoporous silica sorbent for environmental protection applications (i.e., mesoporous spherical-silica particles [MSPs]), was modified by N- [3-(trimethoxysilyl)propyl]ethylenediamine (EDA) solution and was tested for its potential in the separation of carbon dioxide (CO 2 ) from flue gas. The CO 2 adsorption capacity of MSP and MSP(EDA) increased with temperature from 20 to 60°C but decreased with temperature from 60 to 100°C. The mechanism of CO 2 adsorption on both samples is mainly attributed to physical interaction regardless of temperature change. The MSP(EDA) have good adsorption performance as compared with EDA-modified zeolite or granular activated carbon conducted in this study and many types of silica sorbents reported in the literature. The cyclic CO 2 adsorption showed that spent MSP(EDA) could be effectively regenerated at 120°C for 25 min and CO 2 adsorption capacity of MSP(EDA) was preserved during 16 cycles of adsorption and thermal regeneration. These results suggests that MSP(EDA) are efficient CO 2 sorbents and can be stably used in the prolonged cyclic operation. INTRODUCTIONThe carbon dioxide (CO 2 ) capture and storage (CCS) technologies from flue gas are considered to be completely feasible means to lessen the global warming issue. 1 Various CO 2 capture technologies, including absorption, adsorption, cryogenics, membranes, and so forth, have been investigated. 2 Among them, the absorption-regeneration technology has been recognized as the most matured process so far, with the amine-based or ammonia-based absorption processes receiving the greatest interest. [3][4][5][6][7] However, because the energy penalty to regenerate liquid amine or ammonia in the absorption process is high due to the high heat capacity of liquid amine/ammonia and large amount of water, 2 other technologies are being investigated throughout the world. The Intergovernmental Panel on Climate Change (IPCC) special report concluded that the design of a full-scale adsorption process might be feasible. 8 Possible CO 2 sorbents investigated in the literature include activated carbon, 9 -11 X-type zeolites, 12,13 carbon nanotubes (CNTs), 11,14,15 SBA-15 mesoporous silica sorbents, 16 -19 and mesoporous molecular sieve MCM-41. 20 -23 Mesoporous spherical-silica particles (MSPs), which were modified from the MCM-41 materials, 24 are a relatively new sorbent for environmental protection applications. 25 The MSPs possess advantages of much faster preparation time, higher packing density, and lower pressure drop than MCM-41 because of their well -defined spherical shape. 26 These advantages make MSPs more practical
